Support the new gnuefi file locations
Support the new gnuefi file locations

gnu-efi 3.0.11 moves a few files around, e.g.

    /usr/lib64/gnuefi/elf_x64_efi.lds -> /usr/lib64/gnuefi/x64/efi.lds

...and this causes the UEFI EFI helper to fail to link.

Add support for the 'new' paths and fall back to the old ones.
